Preliminary Technical Data
ADUC7030/ADUC7033 ON-CHIP DIAGNOSTICS
The ADuC7030/ADuC7033 integrates multiple diagnostic
support circuits on-chip. These circuits allow the device to test
core digital functionality, analog front-end and high-voltage I/O
ports in-circuit.
ADC DIAGNOSTICS
Internal Test Voltage
The current channel can be configured to convert on an
internal 8.3mV test voltage. On any gain range the result should
be within ±0.5% of the expected result.
Internal Short Mode
The current and voltage input channels can also be shorted
internally. Converting on the internal short will allow an
assessment of the internal ADC noise to be determined.

Internal Current Sources
Internal current sources can also be enabled on both current
and temperature channels. These current sources can be used to
determine external short or open circuit conditions in both
external shunt or temperature sensor configurations.
High Voltage I/O Diagnostics
High Voltage I/O Read back
All high voltage I/O pins will be supported with read back
capability. This will allow detection of external short conditions.
High Voltage Current Detection
All high voltage I/O pins will also have a high current detection
capability allowing high side connections to VBAT to be
detected and controlled.
